arch: Add explicit linker script for u-boot-elf Commit f4dc714aaa2d ("arm64: Turn u-boot.bin back into an ELF file after relocate-rela") introduce REMAKE_ELF option to recreate u-boot.elf from u-boot -> u-boot.bin + DT -> u-boot.elf. The best is to ilustrate it from make V=1 output cat u-boot-nodtb.bin dts/dt.dtb > u-boot-dtb.bin cp u-boot-dtb.bin u-boot.bin aarch64-linux-gnu-objcopy -I binary -B aarch64 -O elf64-littleaarch64 u-boot.bin u-boot-elf.o aarch64-linux-gnu-ld.bfd u-boot-elf.o -o u-boot.elf --defsym="_start"=0x8000000 -Ttext=0x8000000 Last command has no explicit linker script passed that's why toolchain internal linker script is used. In Binutils 2.32 case it contains SIZEOF_HEADERS symbol which has changed behavior by commit https://sourceware.org/git/?p=binutils-gdb.git;a=commit;h=64029e93683a266c38d19789e780f3748bd6a188 which result in situation that program headers has changed from (xilinx_zynqmp_mini_defconfig) Program Headers: Type Offset VirtAddr PhysAddr FileSiz MemSiz Flags Align LOAD 0x0000000000010000 0x00000000fffc0000 0x00000000fffc0000 0x0000000000018918 0x0000000000018918 RW 0x10000 to Program Headers: Type Offset VirtAddr PhysAddr FileSiz MemSiz Flags Align LOAD 0x0000000000000000 0x00000000fffb0000 0x00000000fffb0000 0x0000000000028918 0x0000000000028918 RW 0x10000 Xilinx tools like XSDB or Bootgen are using program headers for loading ELF to the right location and by above binutils change ELF is loaded to incorrect location. The patch is explicitly use u-boot-elf.lds (just cat now) for u-boot.elf recreation which is called when REMAKE_ELF is setup. By purpose u-boot-elf.lds doesn't contain OUTPUT_FORMAT/OUTPUT_ARCH to be able to use by all archs.
